Abstract (en)
[origin: EP0406655A1] This invention relates to a disposable syringe for once-only use. The syringe comprises a hollow cylinder which carries a needle at one end and houses a plunger connected to one end of a shaft, the other end of which is provided with a manually operable shaped head. The diameter of this head is a maximum in proximity to that portion adjacent to the shaft and reduces gradually towards the free end of the head. The shaft length is such that when the plunger has been pushed to the bottom of the cylinder, the maximum diameter portion of the head is housed within the cavity of the cylinder, from which the decreasing diameter portion of the head projects, so that the shaft head can no longer be gripped by the fingers in order to move the shaft backwards and reuse the syringe.
